Answer:
56 students scored in the range of 1301 to 1600.
Step-by-step explanation:
The given question is without any figure or attachment. Here is the figure attached with the answer.
In the figure attached,
total number of students who took SAT = 400
Percentage of the students who scored 1301 to 1600 range = 14% (given in the pie chart)
Total number of students who are in this range = 14% of total number of students
=
= 56
Therefore, 56 students scored in the range of 1301 to 1600.
An arithmetic sequence takes the form
where
is the common difference between terms. You can solve for 
in terms of any of the previous terms of the sequence:
for some integer
Continuing in this way, you know that the sequence can be defined explicitly in terms of the first term
Given that the 4th term is
and the 11th term is 
, you have the following system of equations.
Solving this system for the two unknowns yields
and 
.
So, the sequence is given explicitly by
